Answer:
it is a concave octagon
Step-by-step explanation:
A convex octagon has no angles pointing inward so in other words, the angles cant be acute. A concave octagon has angles pointing inward therefor it is a concave octagon.
Hey!
Answer:
Step 1. The perimeter P means adding up all the four sides of a rectangle.
Step 2. Let w be the width.
Step 3. Let 2w be the length
Step 4. Then, P=w+w+2w+2w=126.
Step 5. Solving yields the following steps
w=21

CF
Step-by-step explanation:
we know that
An <u><em>angle bisector</em></u> is a line that divide an angle into two equal angles.
In this problem
---> given problem
---> by addition angle postulate

CF is an angle bisector of angle 
What was your question that was never answered?
Answer:
The other length is 60m.
Step-by-step explanation:
If you look at the shape of a parallelogram, you will see that a parallelogram has two parallel sides. So, if the total perimeter is 220m, then 50m and 50m together would be 100m, so 220- 100= 120m left to fill in both sides left. so, 120÷2= 60m. 60m is the other length.
